的一部分。例如，这意味着'DEFINES_MODULE' => 'YES'在Swift中不起作用，除非您像这样在Podfile中设置pod_target_xcconfig：
import YLTableView如果我正在编写podspec，是否有任何理由不应该像这样在我的配置中包括DEFINES_MODULE？
:modular_headers => true在我看来，这没有任何负面影响，它使Swift用户可以更轻松地使用我的库。
答案 0 :(得分：3)
存在一个已知问题（具有解决方法）：https://github.com/CocoaPods/CocoaPods/issues/7584。这可能会导致用户直接在其预编译头（* .pch）中导入Objective-C lib头的问题。您可以通过在lib源文件中包含一个空的swift文件来解决此问题。在将来的CocoaPods版本中，可能会有一个干净的修复程序。
否则，没有实际的负面影响。它可以在构建时为导入提供更严格的搜索路径，这意味着：
@import或在Swift中使用import找到它）来自the blog post regarding CocoaPods 1.5.0 release：
[...] CocoaPods允许任何Pod导入具有未命名的引号导入的任何其他Pod。
例如，容器B可能具有带有#import“ A.h”语句的代码，并且CocoaPods将创建构建设置，该设置将允许此类导入成功。但是，如果尝试将模块映射添加到这些容器中，则此类导入将无法进行。多年前，我们试图为静态库自动生成模块映射，但由于它破坏了一些吊舱，因此我们不得不还原。
在此版本中，您将可以选择更严格的标头搜索路径（以及为Objective-C Pod生成模块映射）。作为Pod作者，您可以在pod_target_xcconfig中添加'DEFINES_MODULE'=>'YES'。 [...]
